I have been using webhooks for my project that records the number of pulses made by my household power meter. The Core device uploads the pulse count once a minute. That was until my pseudo-static IP address changed and therefore the website that manages data uploads was temporarily unreachable. I updated the DNS zone files for my domain name with the new IP address and I could access the site again within a few minutes. However, the DNS server used by webhooks server took about a further 8 hours to have the new DNS setting propagated to it and therefore could not reach the target site. At least, that is what I think happened.
I was wondering if there was a way to have the Spark/Particle Core to bypass the webhook server and send an http request directly to my site. That way it would be using the DNS servers specified by my modem/router which would update faster than the DNS server used by the webhooks server. After all, all I want to send is a simple http request of the type: http://www.mydomain.com/reader.ashx?ID=1234&Pulses=10
